Accurate measurement and mechanical parameter extraction of sports based on optical force sensors

Optical force sensors have the characteristics of high precision and non-contact, suitable for mechanical measurements in complex motion processes. This study achieved accurate recording of the motion trajectory and force situation of the target object through the application of optical force sensors. In order to achieve precise measurement of motion and extract relevant mechanical parameters, an experimental system was designed, including optical force sensors, data acquisition devices, and motion devices. Optical force sensors are responsible for real-time collection of force signals received by target objects and sending them to data acquisition devices for processing and analysis. To ensure measurement accuracy, the motion device is designed to control the movement of the target object and provide standardized conditions for the experiment. Signal processing algorithms can filter out noise and interference signals, analyze and interpret the original signal, obtain the motion trajectory and force curve of the target object, and extract mechanical parameters from experimental data. The experimental results show that the measurement system based on optical force sensors can accurately record the force situation of the target object in complex motion processes and obtain detailed mechanical information. Compared with traditional measurement methods, optical force sensors have higher accuracy and a larger measurement range, which can meet the measurement needs in complex motion scenes.
